Before you can proceed, they will need to update their USPS integration. Please have your software provider contact us through API Support to request assistance with their cloud migration.When researching whether a software is properly integrated with the USPS, look for indications such as a reference to the USPS Cloud or Hybrid environment, directions for users to create their accounts on developers.usps.com or the Developers Portal, or documentation indicating that they're calling the endpoints at apis.usps.com.Please let us know if you need additional assistance.Thank you,Frankie | USPS API SupportAPISUPPORT@usps.gov475 L’Enfant Plaza SWWashington, DC 20260From: freeone1@cox.net freeone1@cox.netSent: Tuesday, March 25, 2025 12:16 AMTo: USPS API Support APISUPPORT@usps.govSubject: [EXTERNAL] Webform: On-Prem App RequestCAUTION: This email originated from outside USPS.

It appears that you have created the app using the new cloud-based integration instead of the Prem app integration. We are currently using the prem app integration with our plugin, so I recommend creating the prem app and using this integration with our plugin. * Additionally, you can check the information in the USPS developer guide, which states that existing third-party software (ELEX USPS shipping plugin) can utilize the prem app integration. * [https://prnt.sc/wbW5TQiaQ__k](https://prnt.sc/wbW5TQiaQ__k) * [https://developer.usps.com/getting-started](https://developer.usps.com/getting-started) * [https://developer.usps.com/app-form](https://developer.usps.com/app-form) * Hope it clarifies!
